Overview

 ‘Pump’ is a device that moves liquids by physical or mechanica

includes a bare pump and, as manufactured, mechanical equip

driver, and controls.

Possible Definition of Covered Product

Controls Driver Mech. Equip. Bare PUMP = Pump

 Notes:

• Using the term “manufactured” allows flexibility in application.

- Need to be able to define precisely who is manufacturing rather than moving product- GC requests information about distributors: (1) number, type, engineering expertise applied

ramifications of including or not including distributors.

– (1) Some big, complex packaging. More common are value‐added distributors with 10‐30 pe

be under contract to one manufacturer (instead of sales force). Sometimes just the middle mpump and modify themselves. Manufacturer may state what motor can be paired with pum

specs, and distributor decides, what to package into a ‘pump.’

• Does how we define covered product determine what is pre‐empted? Yes.

- GC to provide information on this for next meeting.- There is a waiver process related to pre‐emption.

 PROPOSAL FOR VOTING: The covered product, a ‘pump’ will be defined as in t

paragraph.

• Vote results: NO VOTE

General Description of ‘Pump’ Components

 ‘Bare pump’ is a device that moves liquids by physical or mech

action excluding mechanical equipment, driver, and controls.

• TBD based on the various pump types/equipment classes conside

coverage.

 ‘Mechanical equipment’ is any component that transfers ener

driver to the bare pump.

• may include belts, gears, couplings, or other equipment.

 ‘Driver’ is the machine providing mechanical input to drive the 

through the mechanical equipment, and may include an electrnatural gas or diesel engine, or steam‐driven turbine.

 ‘Controls’ means any device that can be used to control the dr

including those that automatically adjust the speed of the driv

response to system feedback.

 General agreement in regard to the definitions as written abo

 PROPOSAL FOR VOTING: The components of a ‘pump’ will be d

in the above paragraphs.

 Definition from EU 547:

• ‘Clean water’ means water with a maximum non‐absorbent free 

of 0.25 kg/m3, and with a maximum dissolved solid content of 50 

provided that the total gas content of the water does not exceed 

saturation volume. Any additives that are needed to avoid water 

down to ‐10°C shall not be taken into account.

- In the industry, if a pump is not clean water it says “solids‐handling” 

• There may be separate test parameters related to clean water.

• Start with “clean water.” Check exclusions. Check parameters.

Scope Discussion ‐ Circulator Energy Use Shipments Data

• HI: 1.7 million [1/25‐3 HP, wet and dry]

- likely includes some small pumps that are not circulators

• Advocates: 2 million [0‐1/4 HP]• DOE: 1.5 million [0‐3 HP, wet only]

 Estimated Annual Operating Hours

• HI: 2160 [Provided]

 Average motor draw

• HI: 1/10 HP (78W) [Calculated]

- Does not seem realistic. 78W is less than the operating electric power dr

common “1/25 HP” nameplate circulators. HI survey collected data on 1/circulators.

• Other: 2/10 HP (155W)

- Using the assumption that HI collected nameplate HP and applying 50% e

 Average Load

• Assume power draw is constant across loads

 Annual Energy Use [1 year of shipments]

• HI: 0.285 TWh [Provided]

• Advocates: 1.0 TWh [Calculated]

• Other: 0.57 TWh

- [1.7 mil, 2160 hours, 1/10 HP hydraulic, 50% motor/pump eff]

Scope Discussion ‐ Other Requested Data DOE requested data on the following, but did not receive eno

aggregate the results:

 Circulator Energy Savings Estimates

• Percent shipments variable speed

• Estimated potential energy savings from switching to ECM (cons

• Estimated potential energy savings accounting for variable load

 Other data for circulators:

• Incremental cost of ECM vs AC Induction• Aggregate industry conversion cost• Availability of ECMs

• Testing costs and issues

 Notes:

• DOE to investigate if compliance date can be longer than 5 years • DOE to investigate when DOE can initiate a rulemaking for equip

for which standards are not set in this rulemaking.

 The objective of a metric

• Be objectively measurable• Allow for comparability across models• Focus on energy use or efficiency of the equipment being measured• Limit test burden

• Inform purchasing decisions

 DOE limitations on setting metric

• Must describe energy efficiency or energy use for a covered product

• Must be a single descriptor

 Notes

• Full load or part load or both?

• Manufacturers to discuss the construct and other options.

• DOE to check in with AHRI on 1210 status; look for part load VFD effic

- AHRI to check on rating (not certified) data.

• DOE to do analysis on metric options with the part‐load pump efficie

obtained.

• DOE to present more specifics on metric and testing in March meetin
